- This invention relates to apparatus for I purifying the exhaust of internal combustion engines and particularly of automobile engines, and the object thereof is to provide an apparatus of this class through I which the exhaust is passed and by means of which objectionable odors are removed from said exhaust, and said exhaust is purified so that when finally discharged into the air it will be in a transparent or substantially transparent condition and'free of ob jectionable' odors, carbonic acid gases and other deleterious products produced by the combustion 'of oil or its derivatives, and with this and other objects in View, the in vention consists of an apparatus of the class specified, constructed as. hereinafter described and claimed. a

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of our improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a longitudinal sectional View showing our improved apparatus applied to the muffler of an automobile engine; Fig. 2 a view similar to Fig. 1, but showing a modification, and Fig. 3 a partial section on the line 3-3 of Fig. 1 or on the line 33 of Fig. 2.

Automobiles, as is well known, use internal combustion engines and all machines of this class are provided with mulllcrs, and in the accompanying drawing we have shown at a a muffier of the class and for the purpose specified, and in the practice of our invention we secure to and beneath the truck of an automobile frame and preferably ad.-

ipartments 0, c and 0 are placed in communication by means of ports or passages 0 and a in the bottom portions of the corresponding partitions.

Placed centrally in the compartment 0 is a tube d which extends out through. the top of said compartment and ,down to'the bottom thereof and is provided with lateral discharges cP, and a .pipe 6 forms a communi-. cation between the muffler a and the tube d,

said pipe 6 being connected with or extend- I ing into the top of said tube 03.

In the top portion of the compartment 0 are downwardly directed tubes f which communicate with the compartment 0 through the partition 6 as shown at F, and these tubes f extend downwardly a predetermined distance preferably approximately to the 1 horizontal center of said compartment 0 or above the same, and in the compartment o 1 are similar tubes 9 which communicate with the compartment 0 through the top portion {of the partition 12 as shown at 9 and'said tubes d also extend downwardly and open downwardly to the same extent and in the 1 same manner as the'tubes f. v r In the topportion of the partitionb is an aperture 71, forming a communlcation between the compartments 0 and 0 and in the:

' partition 6 is a similar aperture 2' forming a communication between the compartments '0 and 0 Placed in the central portion of the compartment 0 is arotary fan j and in fan k.- -We also preferably place in the bottom portion of the compartment '0 stirring devices m which may be made in the form of fans or of any other shape, and in the top of the compartment 0 is a filling orifice n and in the bottom thereof a discharge orifice 11?, said orifices being preferably closed by threaded plugs, and in the bottom of the compartment 0* is a drip or condensation discharge a while the compartment 0 is provided in the bottom thereof with numerous perforations n".

In practice a suitable disinfecting and purifying solution 0 is placed in the compartment c and flows into the compartments and and enough of this liquid is pref crably employed to fill said compartments from one-third to one-half of their capacity.

In the use of this apparatus the exhaust from the muflier a passes through the tube bottom portion thereof is a similar rotary e down through the tube d and isdis-' charged at the bottom of said tube into the liquid through which it passes upwardly into the top of said compartment, from which it passes through the'tubes f into the compartment 0 and is directed downwardly onto the surface of said liquid, and said exhaust then passes into the compartment a through the tubes 9 from which it is discharged downwardly onto the surface of the liquid in said compartment after which, it passes into the compartment 0 through the port or passage h, and from which compartment it passes into the compartment 0 through the port or passage 2' and is finally discharged from the bottom perforations n in a pure and transparent or approximately transparent condition. In this operation, the stirrers or fans m in the compartment c agitate the liquid '0 therein and facilitate the passage of the exhaust upwardly .therethrough, and the fans y' and 7c serve to break up and agitate the exhaust as it passes through the compartments 0 and c and to remove therefrom any steam or vapor which may remain therein.

In the construction shown in Fig. 2 the compartments 0 and c are omitted and only the compartments 0, c and c are em- I the compartment ployed. Inthis construction the agitators or fans m are also omitted, but it will be understood that they may be employed if desired. The compartment 0 in this form of construction is also provided in the bottom thereof with a drip or condensation discharge p, and the operation will be readily understood to be the same as with the construction shown in Fig. '1, the only difference being that the exhaust passes directly from the'compartment 'c into the compartment 0 from which it passes into Our invention is not limited to the use of the tubes f and g in the construction shown in Fig. 1 nor to the tubes f in they 1 construction shown in Fig. 2, all that is chlorid of calcium and chlorid of zinc combined in the usual manner.

The automobile is not shown for the reason that it forms no part of our invention, it being deemed suflicient, to indicate the muffler ofthe engine and the form of ourimproved purifying apparatus and to de- I scribe the method of its operation, and it will be understood that the apparatus may 'be'applied to or connected with the truck frame of the automobile in any desired manner. I

It will be understood thatwhile we have described the parts 7', la and m as fans, any suitable agitators may be employed and it will also be understood that the agitators or fans j, k and m may be driven in any desired manner, and from .the foregoing description it will be seen that the compartment 0 is the inlet compartment of the ap paratus or the tank I), while the compartment c 'is the discharge compartment.
